Hi. I have trouble doing things most people would consider pleasant--watching TV, playing computer games, reading. I don't get distracted easily, but when I try to read I can't focus. I feel very restless all the time.

Do I have ADHD? I was on opiates for a while so I've heard it increases your threshold for pleasure, so normally pleasant things no longer feel pleasant. Also I am on an antipsychotic which as we all know decreases the amount of dopamine in the brain and dampens the reward process.

I can't tell if I have an attention disorder, generalized anxiety, or a mood/motivation disorder.

What are the canonical telltale signs of ADHD?
